What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To evaluate the association between endothelial graft failure and total protein levels in the aqueous humor (AqH) after Descemet stripping automated endothelial keratoplasty (DSAEK) in eyes with surgically treated glaucoma. Design: A prospective case series. Methods: This consecutive case series included 181 patients who underwent DSAEK and were stratified into 3 groups: no glaucoma (132 eyes), medically treated glaucoma (17 eyes), and surgically treated glaucoma (32 eyes). The endothelial cell density (ECD) and graft survival rate was compared among the groups and within the surgically treated glaucoma group, among subgroups stratified by AqH total protein levels. Aqueous humor samples were collected at the beginning of each surgery. The levels of total protein and cytokines (interleukin [IL]-1α, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12p70, IL-13, IL-17A, interferon-α, interferon-γ, monocyte chemotactic protein-1, E-selectin, P-selectin, and soluble intercellular adhesion molecule-1) in the AqH were measured by a dye-binding assay or multiplex beads immunoassay. The severity of iris damage was graded based on the number of affected quadrants (range, 0-4). Main Outcome Measures: Graft survival over 6 years after DSAEK in relation to preoperative AqH total protein levels and its association with postoperative ECD. Results: Best-corrected visual acuity significantly improved after DSAEK in all groups. However, ECD after DSAEK was significantly lower in eye with surgically treated glaucoma, compared to eye without glaucoma ( Conclusions: Higher preoperative total protein levels in AqH were associated with poor graft survival after DSAEK for bullous keratopathy after glaucoma surgery.
